Tohllwhom-it may concern.-

Be it known that I, KARL GUSTAF WVERNER Gnonnunma subject ofthe King of Sweden, residing at Skara, in the Kingdom of Sweden, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

"Theflpresent invention refers to refrigerators and has for its object to provide simple.

means for lowering the temperature in the chamber of the refrigerator containing the food and the like, and for causing an effective ventilation thereof, so that the refrigerator may be freed from musty and foul air. The invention is substantially characterized by means being provlded for forcing air from the ice-chamber to the food chamher of the refrigerator.

wall of the ice-chamber, which through suitable channels or passages communicates with the chamber for the food or the like, a pumpingadevice or the like, by which cold air by a simple manipulation can be forced ift'rom the ice-chamber to the chamber for the '00d.

Preferably a part of the upper wall or cover of the refrigerator is formed as a pump plunger, the ice chamber being located immediately below said wall or cover.

An embodiment of the invention is illustrated in the accompanying drawing.

Figure 1 is a vertical section of the refrigerator and Fig. 2 a top plan view thereof. a

a indicates the outer side wall of the refrigerator, (Z the door, I) the main bottom and c the cover. These parts a, b, 0, cl, thus form the outer framework, which suitably is made of wood. At the inside of this framework there is arranged an inner wall 6 of sheet metal, which is provided with an opening f opposite to the door ti, and further with a lower bottom 9 and an upper bottom it. In the chamber above this upper bottom the ice or other refrigerant is placed. Between the outer wall or frame-work and the inner wall (Z of sheet metal with the bottom 9 there is provided a space or channels j, which partly through a central opening is in the bottom 9 communicates with the chamber at below the bottom it, in which chamber the victuals or goods are to be inserted, and partly through holes Z in the upper end of the metal wall with the the. ice-chamber m.

ice chamber. The air in the ice-chamber thereof, y p p The cover c of the refrigeratorus provided with an opening, which has aboutthe same size and form as the crosssection of At the upper edge of this opening there is provided a lid n which by suitable hinges is swingably connected to the cover 0 and provided with a downwardly projecting flange 0. This flange fits tightly against the packing p, which is attached to the wall of the opening in the cover a. The lid is provided with an airopening, which is controlled by a springactuated valve The lid n then forms a plunger, so that, when it is turned up and down, cold and fresh air is forced from the ice chamber through the holes Z, passages j and the opening is to the food chamber m,

whereby the refrigeration of this latter is promptly and highly increased, the old and foul air in the food chamber simultaneously being caused to pass out through the holes r in the inner sheet metal wall or lining of the door, further through the passage 3 between said lining and the outer wall of the door and finally through the hole a: in the outer wall of the door.

Preferably the opening in the cover a is provided at its lower edge with a bottom 2, provided with an opening, controlled by a spring-actuated valve 71. When the plunger or lid by means of the handle 8 is moved upward the valve 9 is opened and the valve ?I closed, and when the plunger is moved downward the valve 9 is closed and valve i opened. By the arrangement of the valve 21 it is thus surely secured, that the air in the ice chamber does not flow out through the cover, when operating the plunger. It will be understood, that in operating the lid or plunger n this may not be turned so high, that the lower edge of the flange 7) will reach above the upper surface of the cover 0. The water in the ice chamber can be withdrawn through the cock 2?.

It will be understood that the construction above described can be modified in many ways without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. In a refrigerator, a chamber for the refrigerant, arranged at the top of the refrigerator, a chamber for the food, arranged below the refrigerant chamber, air passages between the two chambers, and means for forcing the air from the refrigerant chamber to the food chamber, said means comprising a lid, having an air valve and a flange, which fits tightly against the edge of an opening in the wall of the refrigerant chamber.

2. In a refrigerator, a chamber for the refrigerant, arranged at the top of the refrigerator, a chamber for the food, arranged below the refrigerant chamber, air passages between the two chambers, the'top Wall of the refrigerator being provided with an opening of about the same form and size as the horizontal section of the interior of the refrigerant chamber, a lid being hinged to said wall and provided with a flange, fitting tightly against the edge of the said opening,

a bottom being arranged at the lower edge:

of said opening, said lid and bottom being provided with valve-controlled air passages. In testimony whereof I have alfixed my signature in presence of tWo Witnesses.
